Win an extra spin for free if a Free Spins symbol lands on screen.
Free Spins Bonus
To initiate the Free Spins Bonus, three Bonus symbols must land.
One randomly selected symbol will turn into a Special Expanding symbol, and this then expands and will cover the entirety of the reel.
Across any win lines, the Special Expanding symbols will be paid as a Scatter symbol.
If you land a greater amount of Bonus symbols when you activate Free Spins, the Special Expanding symbol will be a better type.
